Controlled variables are quantities that a scientist wants to remain constant and observe as carefully as the dependent variables.
what does controlling the variable mean?
== ==
Controlling variables is when you make sure that only one variable is being tested at a time and that there are not other variables that will make your results unclear. Using a control is when you do a trial without the variable to see what the normal results are.
So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
Dependent (Responding) Variable
it will die or prolong cell life
laboratory experiment
independent variable can be controlled by manipulation or selection.
Controlling other variables means keeping all factors constant except the independent variable being studied in an experiment. This helps to isolate the effects of the independent variable and determine its true impact on the outcome. By controlling other variables, researchers can ensure that any changes in the dependent variable are a result of the independent variable being tested.
To eliminate alternative explanations for the result of an experiment
You can control independent variables in an experiment. These are factors that you deliberately change in order to observe their effect on dependent variables, which are the outcomes you are measuring. By controlling independent variables, you can help determine cause-and-effect relationships.
Controlling variables in an experiment is important because it allows researchers to isolate the effects of the independent variable on the dependent variable. This helps to ensure that any observed changes are actually due to the manipulation of the independent variable, rather than other factors. Controlling variables also helps to increase the reliability and validity of the study results.
